TO ALLWHOM IT MAY concerns:

Be it: known that I, IRA A. SALMON; of Boston, in the countyof Suffolk,and State of Massachusetts, have made a new and useful Instrument Rackfor Dentists Tools;- and I do hereby declare the following to be a full;clear, and exact'description of the nature, construction. and operationof the same, suiliciout to enable one skilled in the-art to which itappertains to construct and use the some, reference being had tothe-accompanying drawings, which are made part of this specification,and in uhich i Figure 1 is a. plan view; and Figure 3 a side elevation.I

Figure 2'is a transverse section at a b, fig. 1. Figure 4 is atransverse section at'd e, fig. i.

The improvement consists of a tray or cushion having upon it a series ofwedge or chisel-shaped projec tions, between or upon which the toolsbelonging to'the dental mallet are placed, so as to be readily detachedthereby from the stock of the mallet and retained in convenient positionfor being again attached.

H In the'drswings, A is the tray, cushion, or platform, in whichisiirmly embedded the lower part of a rack, whose projecting elevations,n n, 0 0, are oi a wedge or chisel shape, for reasons to be explained.'It is necessary, in connection with the dental mallet, to have avariety of pluggers, which require frequent changing, and 'itbecomessquatter of'conv'enicncc and economy of time to have ameans ail'orde'rlfor-instantly detaching them from the stock, leaving them-in position tob readily accessible. he" shanks are eitlrcr'soch'etcd or screwed'ilitov the stock, and in my rack the means are afforded for the removalof either. To begin with those which are merely slipped into thesock'etof the hammer-stock The shank of each tool has upon it two flattenedportions at opposite sides; it also has a hole through this flattenedportion, which hole and flattened portion of the tool (when in thesocket) entenpartly into the socket, only leaving them partly in sight.T his hole is slipped down upon one of these chisel-shaped or bevelledpins 0 0 until the end of the socket strikes the thick part of the pin,i when, by a downward movement of the case, the pin acts as alevcr,prying out the tool, the end of the socket i being the fulcrum. Thisflattened portion is laid into the notch betwecrr two of' theprojections]: n, and by pressure downwards, the wedge pressing againstthe shoulder of the plngger and the end tho-stock, the tool is withdrawnand lies in the interval between the projections 1i n,ready to wbe sgainattached when required, the j projections'n n embracing it at thenarrow or flattened portion, not allowing it to slip out longitudinally.A little depression of the case will cause the projections o o and n nto act as lovers in withdrawing the tool from the-stock. In case thetool is screwed into the stock the hole is slipped over one of the pins0 or the flattened part into one of the slots )1, and the stockbeing-rotated, the tool is detached and left upon the projection or inthe slots 1;, ready for being again attached to the stock when required,.as shown in fig. 3, p 1. Y

"I make no claim to a tool-rack as represented in the United StatesPatent No. 54,8 2; but what I do claim as my invention, is-- e I i Atool-rack or instrument-rack made of steel pins,bevelled on one side, inthe manner and for the purpose hereinbet'orc described. v

I also claim, as an improvement on United States Patent No. 54,882, orany such rack, the construction of the teeth, bevelled, wedge or chiselshaped, substantially as and for the purposes and objects ashereinbcfore' specified, g

To the above specification of an improved dentists instrument-rack Ihave signed in hand this second day of Jane, 1865.
